I love Valve's games, whenever I actually sit down and make something out of LEGOs it's usually a replica of something from those games. Whether it be Half-Life 2 or Portal. I don't build stuff very often or keep what I built for very long. Whenever I use a lot of resources to make something I will take pictures and upload them, but when I want to make something new that I feel would be more important at that moment I scrap whatever I need to make it. The only things I keep no matter what are the Model city sets (like Green Grocer), or vehicles/creatures I recreated that I worked really hard on (like my Jalopy).
I love to do Minifigs too, I usually keep all of those in one piece. I love classic LEGO sets, old Pirates castle or space, although I do not have many of them. I do some tutorials on youtube, if I ever upload something that I've done a tutorial for I will put a link in its description ;)
Thanks for reading! I hope you enjoy what I made. I can guarantee that every single thing I upload had at least one piece that I spent an hour looking for ;)
